Patent number: 10260588Abstract: A method and a device for damping relative motion between structural elements (4a, 4b, 5), and in particular for damping oscillations in a stay cable of a building or a civil engineering structure. A damping device is disclosed which provides motion damping by means of frictional engagement (1a, 1b) between friction surfaces composed of low-friction polymeric material (2a, 2b, 3a, 3b). The polymeric material preferably includes a dispersed lubricant. The use of low friction polymers results in a constant damping which is effective over a broad range of displacements and forces.Type: GrantFiled: December 23, 2009Date of Patent: April 16, 2019Assignee: VSL International AGInventor: Yves Bournand

Patent number: 7814600Abstract: The invention relates to a corrosion protection system for a stay cable construction including a multiplicity of tension members made of parallel steel tensile elements, extending between a first anchorage and a second anchorage, and comprising two opposite ends, the first end co-operating with the first anchorage and the said second end co-operating with the second anchorage. The corrosion protection system involves the use of tensile elements which are not provided with a permanent corrosion protection during their fabrication. This corrosion protection system includes: a plurality of stay pipes, each freely surrounding a tension member made of unprotected tensile elements, a dehumidification device which produces dry air, supply pipes supplying the dry air to predetermined points situated on the first anchorage, the second anchorage, and the stay pipes, a ventilation device pushes the dry air in the supply pipes, surveying, measuring, controlling and testing facilities.Type: GrantFiled: November 12, 2004Date of Patent: October 19, 2010Assignee: VSL International AGInventor: Yves Bournand
